Three-dimensional imaging system for colonoscopy.

چکیده
Three-dimensional (3D) imaging techniques have been developed in the medical field. In laparoscopic surgery, such techniques are widely used; they provide the surgeon with spatial information and increase the safety of surgical techniques [1–3]. In gastrointestinal endoscopy, Sakata et al. reported the efficacy of 3D imaging for improved detection of colonic lesions using simulated 3D colonoscopy [4]. However, to create a conventional 3D image, two optical axes are required. A novel 3D imaging processor (HD-3D-A; Shinko Optical, Tokyo, Japan), which can create 3D virtual video images from conventional two-dimensional (2D) endoscopic video images, has been developed recently [5]. This imaging processor is connected to a monocular endoscopic system and converts conventional endoscopic images into a pair of images, as if they were obtained from two different points that match the operator’s convergence angle [4] (▶Fig. 1). This system can be used in combination with a conventional endoscope, and 3D images can be easily viewed using 3D glasses and a 3D monitor. Here for the first time, we report the use of this 3D system in gastrointestinal endoscopy. In gastrointestinal endoscopy, the 3D image also provides the endoscopist with space perception, helping them to evaluate the status of the intestinal tract space (▶Video1). In addition, we can more precisely visualize the

Fabrication of New 3D Phantom for Measuring Geometric Distortion in Magnetic Resonance Imaging System
Introduction: Geometric distortion is a major shortcoming of magnetic resonance imaging (MRI), which has an important influence on the accuracy of volumetric measurements, an important parameter in neurology and oncology. Our goal is to design and construct a new three- dimensional phantom using a 3D printer in order to measure geometric distortion and its reproducibility in...
متن کاملVirtual vs. optical colonoscopy in symptomatic gastroenterology out-patients: the case for virtual imaging followed by targeted diagnostic or therapeutic colonoscopy.
AIM To compare virtual colonoscopy with optical colonoscopy findings in symptomatic patients. BACKGROUND Computer tomographic colonography is an alternative to optical colonoscopy. Studies have shown that two-dimensional computer tomographic colonography does not have sufficient sensitivity. Three-dimensional computerized tomographic virtual colonoscopy compares well with optical colonoscopy ...
